BEARING-BOX.

SPECIFICATION forming part of Letters Patent No. 465,673, dated December 22, 1891.

Application filed March 25, 1891.

To all whom it may concern.-

Be it known that I, EDWARD D. MACKIN TOSH, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Bearing-Boxes, of which the following is a specification.

My invention relates to an improvement in bearing-boxes for shat'ting in which provision is made for adjusting the bearin g up and down with great precision in order to secure its perfect horizontal alignment A practical embodiment of my invention is represented in the accompanying drawings, in Which- Figure l is a View of the box-frame showing the bearing therein in end elevation. Fig. 2 is a top plan View with the upper portion of the frame and adj usting-screw removed, and Fig. 3 is a View in vertical section taken longitudinally through the bearing.

A represents the base of the box-frame, a the two side standards, and a the top or crosshead. The part a is removably secured to the upper ends of the standards a by nieans of screws B. The lower half-bearing is represented by 'O and the upper halflbearing by O. The lower half-bearingOis shown in the present instance as provided with laterallyprojected lugs 0, two upon each side, adapted to embrace the opposite sides of the standards a, as .clearly shown in Fig. 2. justing-screw D, provided with a jam-nut d, is seated in the top a and projects downwardly into position to hold the upper halfbearing 0' in position and to prevent the upward displacement of the shaft.

The parts which I have thus far referred to are well known in the art, the particular forms which I have herein shown being selected for the purpose of showing the practical application of the adjusting device which forms the particular subject-matter of my present in- An ad- Serial No. 386,311. (No model.)

the shaft therein will be elevated or depressed.

Through the side of the baseA an adj ustingscrew F extends, bearing atits inner end against the side of the bevel-faced supportingpiece E, the said screw being provided with a jam-nutf to secure it in the desired adj ustment. By turning the screw F in the direction to makeit enter the base it will force the bevel-faced support E upwardly along theincline e, and by turning it in the opposite direction it will lower the same.

It is obvious that the frame with its beveled-faced support and screw might be reversed to form a hanger-support instead of a standard-support, as herein represented.

\Vhat I claim is- The combinatiomwith the supportingt'rame or hanger provided with an incline side and the bearing having a movement therein relative to the frame, of a bearing-support having an inclined face adapted to engage the inclined seat upon the frame, and an adj ustingscrew seated in the frame and having an engagement with the inclined-faced bearingsupport to slide it along the inclined seat in the frame and thereby raise the bearing within the frame, substantially as set forth.
